- Torque: 225 lb-ft @ 3,000 RPM
- Fuel System: Multi-port fuel injection
- Compression Ratio: 8.8:1
- Bore x Stroke: 3.88 in x 3.41 in (98.4 mm x 86.7 mm)
- Fuel Economy (approx.): 14-16 MPG city, 18-20 MPG highway (actual results vary widely based on condition, modifications, and driving style)
This engine is known for its low-end torque, which is fantastic for off-roading, crawling over obstacles, and pulling loads. It’s a simple, robust design that, with proper maintenance, can easily last well over 200,000 miles, sometimes even 300,000 or more!
Transmission Options: Auto vs. Manual
The 2001 Sport offered two primary transmission choices, each with its own advantages:
- Automatic Transmission: Aisin-Warner AW4 4-speed automatic. This is the most common and highly regarded automatic transmission for the XJ. It’s known for its durability and smooth shifts.
- Manual Transmission: New Venture Gear NV3550 5-speed manual. While less common, this manual transmission offers more direct control and can be preferred by purists and those who enjoy precise gear selection, especially in technical off-road situations.
Both are solid options. The AW4 is often praised for its ability to handle abuse, while the NV3550 provides a more engaging driving experience.
Transfer Cases: Command-Trac vs. Selec-Trac
The transfer case is what allows your XJ to switch between 2WD and 4WD. Two main types were available:
- NP231 Command-Trac: This is a part-time 4WD system. It offers 2WD High, 4WD High (part-time), Neutral, and 4WD Low (part-time). Crucially, 4WD High should only be used on loose or slippery surfaces, as it locks the front and rear axles together, which can cause driveline binding on dry pavement.
- NP242 Selec-Trac: This is a full-time 4WD system. It adds a “Full-Time 4WD” option, which allows you to drive on dry pavement in 4WD as it has a differential that permits speed differences between the front and rear axles. It also offers 2WD High, 4WD High (part-time), Neutral, and 4WD Low (part-time).
For serious off-roading, many prefer the NP231 for its simplicity and strength, though the NP242 is excellent for varied conditions, especially if you encounter snow or ice regularly on paved roads. Understanding these 2001 Jeep Cherokee Sport specs tips is key to proper operation and preventing driveline damage.
